Problems with Aftermarket Oil filters -- Pics -- MUST SEE

[Cal330ci]

Hey guys,
I have done a couple threads for the local forum in my area but now that I am on here its probably a good chance to show some important articles with good information.
This one about aftermarket oil filters and a few problems I have had with them. The most concerning is the example in the pic and how new filters were collapsing even under normal oil pressure. I have seen quite a few like the one in the pic. If you do not change your oil then you probably never what your old filter looks like. With the filter collapsing it can restrict oil flow and when it collapses its now shorter and oil can flow around the filter. The oil now is flowing unfiltered.
Also the O rings you get with the filter usually leak, some of them very severely. This obviously causes low oil pressure, low oil levels and other problems related to excess oil on rubber components etc...
For the record I have never had a problem with OEM filters.
